Police arrest 1 in Los Angeles family slayings

Flowers and votive candles are seen outside the home of the owners of a family-owned business, United States Fire Protection Services, in Downey, Calif., on Thursday. A gunman killed three people and injured two, including a 13-year-old boy, Wednesday in two separate attacks on a family at its suburban Los Angeles business and nearby residence. Police say the five family members who were shot had been targeted by the gunman.

DOWNEY, Calif. — Police said Friday they arrested a man who matched the description of a gunman who killed three people and injured two others in suburban Downey.

Police Sgt. Maria Villegas confirmed the arrest after the man had been detained and questioned. The man's name and age were not immediately released.

Authorities brought the man in after a black Camaro that was stolen was found following Wednesday's shooting at a family owned fire extinguisher business and a relative's nearby home.

Police haven't given a motive but they said they don't believe the killings were a random act of violence.

The three people killed were Josimar Rojas, 26, Irene Cardenas, 35, and Susana Perez-Ruelas, 34.

Rojas and Cardenas were killed at the business, United States Fire Protection Services Inc., where another woman was wounded, the Los Angeles Times reported. She remains in stable condition.

The gunman then went to the home of the business owner a few blocks away and killed Perez-Ruelas and wounded her 13-year-old son.

A portrait emerged of a tight-knit family who threw large parties and ran a successful company.

Prayer candles and flowers were left at the home and nearby business where the shootings took place. A sign decorated with pink hearts and flowers was left outside the house, reading "RIP Susana, to a great mother."

There was no sign of forced entry at the business or home, and police believe the suspect spoke with the victims at both locations before the shooting began.
